Combination Cooking
Combination cooking is achieved by operating the microwave
and heater modes together during one cooking cycle. There
are three combination modes.
1. Combination (convection and microwave)
2. Combination (grill and microwave)
3. Combination (grill, convection and microwave)
The digital programmer circuit operates the power relays as
shown in the figures below.
When the oven temperature reaches the predetermined tem-
perature, the digital programmer circuit stops supplying power
to relay (RY5) resulting in the convection heater turning off.
During this time the digital programmer circuit continues to
operate relay (RY1) so that microwave activity continues at the
duty cycle selected. The inverter control signal level is also
maintained. The microwave activity continues to cycle until the
entire cooking program is completed.
When the oven temperature drops below the selected tempera-
ture, the digital programmer circuit operates power relay (RY5)
switching on the heater elements.
In the case of grill combination the sequence applies with the
digital programmer circuit switching power relay (RY4) to con-
trol, the grill elements.
With convection, grill and micro power combination. The grill
elements and convection elements are operated alternatively
whilst the oven temperature is above the selected level.
